Count me as another Fluke fan, I started with the Fluke 77 in the 
Navy, and as a result bought a Fluke 77 III.  It's the one piece of 
test equipment that I use the most.

I'm not sure where Richard lives, but anyone looking into 
Oscilloscopes or meters that lives close to a Fry's might want to 
consider checking them out.  They're where I got my Fluke 77 III and 
Tek TDS-220 from, and at least the one near me seems to always have a 
good selection.

Something else I added to my assortment of test equipment in the last 
year or so was something I've always wanted, though I have to 
question my need for it, and that's a clamp-on Amp meter.

The next pieces of test equipment I'm likely to be looking at will be 
a Variac and a Oscillator.
